A. oblongum, A. meyeri, and A. ridleyi are exponents of one single species, only differing in sizes and in facies, as there seem to be sufficient intermediates to connect them. However, we do not believe this, as it readily appears incredible to unite e.g. ‘typical’ A. ridleyi from Singapore, a plant with robust twigs, with A. meyeri, a plant of much more delicate stature, from Luzon. On the other hand, also A. javanicum (a species with obvious hairy leaf bud, and small fruits, 15–20 mm long), seems to intergrade with A. meyeri, typically with an indument of minute scale-like hairs. In this way, the ‘ javanicum complex’ problem, as alluded to in the introduction, is replaced by a smaller ‘ oblongum complex’ problem which again needs further study; probably some more not yet defined taxa are involved.</p><p>3.
